In order for you to float, the water that moves out of the way to make room for you must weigh as much as you do. Since you are lighter (less dense) than water, the water pushes you up enough for you to float.
The Dead Sea has a LOT of salt in it. Salt water is heavier (denser) than regular water. People can float in regular water, but since salt water is even denser, it is even easier to float in the Dead Sea.

Did you ever notice that when something floats in water, part of it is actually under water? As it sinks (even a little bit) it pushes away the water until that amount of water weighs the same as the thing that is floating. If the thing you try to float is too heavy, it cannot push away enough water to be the same as how much it weighs. If that happens,the thing will sink.Ask an adult to help you with an experiment (a test) that can show you how this works: Float a small plastic boat in water and notice how deep the boat sinks when it is empty. Then add pennies to the boat and watch how the boat sinks deeper and deeper the more pennies you add. The pennies make the boat weigh more and more. If you add enough pennies, the boat will sink deep enough so that water reaches the top and then the whole thing sinks.Blow up a balloon and float it on water. It will not sink very far because it is not very heavy. If you look really close, where the balloon touches the water, you can see a little dent in the water under the balloon. That's the place where the water is pushed out of the way. If you try this test with a ball that is exactly the same size as the balloon, the ball will sink deeper before it floats. Because the ball is heavier than the balloon, it has to push more water out of the way before it can float. It is not just how heavy something is that makes it float or sink. Look how heavy real boats are -- and they still float. Floating or sinking has to do with the amount of water pushed out of the way. Any boat will sink if you put enough stuff inside it -- just like your experiment showed. Small, heavy things like a marble or a rock cannot float because they cannot push enough water out of the way to be the same as how much they weigh.. So remember, anything that floats weighs the same as the water pushed out of the way. P.S And 1 more thing, Objects that are heavier than the same amount of water will sink. Things that are lighter than the same amount of water will float. If you push an empty bottle under water, you push a lot of water out of the way. That water would weigh much more than the bottle. The bottle will float. A rock put under water also pushes a lot of water out of the way. That water would weigh less than the rock, so the rock can sink. I hope this answers your question!!!!

The Dead Sea is highly concentrated with salt. The density of the water in the dead sea is higher than the the human body. Therefore, people float in the dead sea.

Just like you do in any other body of water only easier. Your body is actually less dense than the amount of water it displaces. Which is the requirement for something to float. You have to displace more water than you take up. That's how WWII ships made out of concrete were able to float. They may have been heavier, but they were able to displace the water.
Also, the Dead Sea is much saltier making it more dense and therefore you're even LESS dense and so you float easier.

The high concentration of salt not only creates buoyancy in the Dead Sea but makes the water too salty to sustain an ecosystem, ergo "Dead Sea"

The flak jacket you'll need will help you float. Seriously, it's the high salt concentration in the water.

It's best on your back. That way you can breathe while you float.

The high concentration of salt makes you more bouent.
